A golden day for Great Britain's sailors in Tokyo saw Giles Scott recover from a nightmare start to successfully defend his Finn title while Dylan Fletcher and Stuart Bithell claimed the narrowest of victories in the 49er.
There was also a silver medal for John Gimson and Anna Burnet in the mixed Nacra class, with Hannah Mills and Eilidh McIntyre poised for gold in the women's 470 on Wednesday.
Scott was Britain's banker on the waters of Enoshima on Tuesday, which thankfully were raceable after the previous day's hiatus due to a lack of wind.
They had hoped to make it a double medal celebration but Dobson and Saskia Tidey had to settle for sixth place.
Fletcher admitted they have a lot still to do, saying: "We haven't even invited everyone, we haven't done suits, there's so many things that most people sort out that hopefully maybe Charlotte will do."
Silver behind the Italian pair of Ruggero Tita and Caterina Banti looked by some way the most likely outcome for Gimson and Burnet and so it proved in a far less dramatic race.
It was a hugely emotional moment for 38-year-old Gimson, for whom this was a long-awaited Olympic debut.
He said: "Twice my discipline got dropped as a class. The second time I'd sold my house and had literally no money and at that point I was questioning my life decisions but it was all worth it, all of it."
